Researchers over at Cynet and BugSec were the ones behind this rather severe vulnerability, which was found in the ‘Smart Notice’ app that arrives pre-installed on the LG G3. Well, now that LG has already issued the patch, all you owners of the LG G3 might want to make a beeline for this patch so that you do not end up being a victim of a phishing scam where your smartphone is concerned, and then some. Not only that, if you just crawled out from a cave somewhere, also take note that LG is kind enough to have started to introduce an update which will ensure you are rocking to Android 6.0, Marshmallow rather than Lollipop.
This is one particular case where delaying the patch application is not encouraged for obvious reasons. You can access the update by navigating to Apps -> Update Center -> App Updates, and it should be found.
